Bathroom floor.

[DP]

Going to get the bathroom at daughter's flat remodeled.

Bathroom has been cleared out with a view to get the floor 'tanked', tiled or covered with material for added protection to spills etc during showers and washing.

Floor is concrete bison with straps lad atop. These straps were then sheeted with chipboard flooring. My first thought was to get the floor tiled wall to wall (with upstands at the wall) to then fit the sanitary ware. The problem with this idea is that the floor gives on account of straps that are not attached to bisons, only laid on top. Therefore, the tiled floor will give leading to cracked floortiles.

Have seen vynil flooring that sweeps up to what would be the shirting giving a floor that will contain odd spills.

Can anyone please suggest what is the best way forward?

Chipboard is unsuitable for tiling, overboard with ply or aqua or wedi board.

Thanks for posting foxhole.

Sheeting the floor will not be sufficient as floor will still flex after chipboard is dressed with plywood sheet or other material on account of construction of floor.

Could you explain? a 25mm ply floor screwed securely should produce a floor that even unsupported should not flex enough to disrupt tiling, what size room?

Bathroom is 1800 square.

25mm ply with tiles on top- will that not creat quite a step?

I have used said ply before but laid it in place of T&G flooring on proper suspended flooring with tiles to finish. As such there is almost nil level difference between carpeted hall and tiled bathroom flooring.

In the flat the chipboard flooring is laid on top of 25x50mm straps (guessing). Because the floor is 'floating' and looking for answers is the reason for posting.

I will sugest what you say to my daugter and see if she is willing to go for height difference between hall and bathroom. Would I be right in thinking the ply sheet and tiles on top will be about 35mm higher than the hall floor?

I'm afraid if the floor is not rigidly supported, even 25mm WBP will flex enough to cause tile failure; You will either have to ensure the floor is fully supported or switch to plan B, Vinyl.

Unfortunately I'm not familiar with your type of floor construction & you posted no pics to give any clues which is the reason why I have not posted before; if I get time I will look it up & see if I can make a suggestion.

Tiled a relatives home with same construction, no prolems as the timber batons are usually 400mm centres or closer. You could remove the floor back to concrete and use ply screwed and glue to bring back to required level.

Sorry but you said unsupported, where did the timber battens come from & what is supporting them?

Any type of floating floor is generally a problem for tiles & they are not suitable unless additional work is undertaken to stiffen the floor considerably & to anchor the tile base to the floor in order to stop it from moving!

Sitting on timbers according to poster, these are either just sitting on the concrete or sometimes glues down.It's treated as a floating floor as even if glued this can fail allowing minor movement.Should get very little movement on a small area like that.
